I couldn't find anything suitable in the internet, so I built one on my own in this way:

Using a steel rod of about 8 mm diameter.

I tried to mill three teeth with equivalent distance around the boundary of one end of the rod with an angle grinder. After that I drilled a hole perpendicularly in the center of the rod. Taddaah... a working screwdriver!

Now let's begin the Teardown.
